Thanks for reviewing!

We really appreciate your review. Spread the word and share it with your friends.

I found in my IT data room a Belkin 550VA UPS which the battery was no longer good; I was able to find a replacement battery quickly at Staples Business Advantage and it shipped quickly; received it the next day. Very happy with what Staples Business Advantage has to offer - a lot of variety. Thank you.

My UPS was about 3 years old and kept beeping when the power was interrupted. After some troubleshooting, it was discovered that the battery was not holding a full charge. Unfortunately, my local Staples did not carry the battery in stock, so it was ordered online and arrived in two days. Changing the battery was very simple. Once installed, and after a day of charging, I simulated several power interruptions and the UPS did not beep and performed as it should. So if your UPS is beeping, try a new battery!

This replacement battery cartridge works as good as new. The challenge was finding which replacement battery cartridge was the right one for our APC power back-up unit. This battery is very heavy; it weighs a ton, and is most of the weight of the back up unit itself. This unit is not suitable for travel because of it's extreme weight, even though the unit is compact. This battery is the replacement battery pack for the APC Back-ups ES725 Battery Back UP PLUS Surge Protection unit.
